The report describes experiments and theoretical analysis concerned with sandwich combustion. The ingredients used in the experiment are compacted polycrystalline ammonium perchlorate as the oxidizer, hydroxyl terminated polybutadiene as the binder and four catalysts Harshaw catalyst CU-0202, Fe2O3, ferrocene, and iron blue. The pressure range studied is 600-2000 psia. The experimental techniques used are cinephotomacrography for sample observation during burning and burn rate determination, scanning electron microscopy for observation of quenched samples, and electron microprobing for an exploratory study of surface compositon. A theoretical solution to a simple sandwich deflagration problem is attained. The probable sites of catalytic activity are determined, results are compared with actual propellant experience, and the analysis is used to clarify experimental results. Author
